Error when install postgresql on fedora- Silverblue

Dear all,
I’ve Fedora 32.(Silverblue), when install postgresql -server
sudo dnf install postgresql-server sudo postgresql-setup --initdb
The Message Error
System has not been booted with systemd as init system (PID 1). Can’t operate.
Failed to connect to bus: Host is down
FATAL: no db datadir (PGDATA) configured for ‘postgresql.service’ unit

You are inside a toolbox, right?

Yes l’m inside toolbox

This won’t work. There are limitations on systemd services inside Toolbox. sudo systemctl enable postgres isn’t a thing inside the Toolbox image (or at least it’s limited in what it can do). I’m developing a Rails app, and I do all my local setup in a Toolbox and install everything there - except Postgresql. I run Postgresql as a separate Podman container. The app can talk to the container through the port, so the rest of the setup is transparent.

This oneliner downloads and runs the container (replace CONTAINERNAME and username, obviously):

podman run --name CONTAINERNAME -p 5432:5432 -dit -e POSTGRES_HOST_AUTH_METHOD=trust -e POSTGRES_USER=postgresuser -e POSTGRES_PASSWORD=postgres docker.io/postgres:12-alpine

If you need manual setup (role or db creation, psql commands, etc), run a bash session inside the container:

podman exec -it CONTAINERNAME bash

After this, start with podman start CONTAINERNAME (or stop or restart or rm (if you want to delete and start over)).
